The co-crystal structure of NolR with a 22-base pair operator sequence (Oligo AT) reveals how the repressor recognizes its target. The NolR dimer binds to an asymmetric operator site. | The co-crystal structure of NolR with a 22-base pair operator sequence (Oligo AT) reveals how the repressor recognizes its target.
